SOURCE: Idle Problem when you slow down of come to a stop idle goes low

THis has happened to me in the past. My fix was to clean the throttle body. The problem began after my battery died. The computer was defaulted back to its original settings after replacing the battery. Once I cleaned the throttle body, everything was fine. This happened at about 85,000 miles.

SOURCE: Tahoe shuts off during idle time...

Your idle speed is either too low or your ECU is not sensing it correctly. The dealership would have to help with either of these. Other than that you may have a weak or bad fuel injector that is not pumping gas to the motor.

SOURCE: After disconnecting trhe battery in my 2004

This is one of the most common problems with our TB's. All you do, is clean your throttle body with carb cleaner, with the battery disconnected. Cleaning the throttle body is a must to fix this problem. Then hook the battery back up and drive for around 5 miles, you're problem will be fixed.

Testimonial: "This is the solution that really and completely restored my vehicle. Thanks so much. "

The engine shut down while on stop and go traffic. Tried to restart but the throttle was weak and shut down again. After shutting everything down for 5 minutes, restarted the engine. The throttle w

If the car is having trouble maintaining idle (the tach dips and car dies) the common causes are the idle control valve and camshaft position sensors. The cam sensors failing will be indicated by a check engine light.

The ICV can removed and cleaned with good results (I think there is a write up on bimmerfest) or purchased new for about $100.

While you are in there check the intake boot that is Y shaped for cracks, it's prone to fail and will mess up your idle too.

Idles up and down when my 2003 trailblazer is in nuetral

Here is the common problem and fix.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1999 CLK320 occasionally just shuts down for about 10 minutes

I had the same problem with the same car year and make.. it ended up being a "rev sensor" something like that or an "idle" sensor".
